Original job description

The Red Gate Group is seeking a talented and motivated Physicist to support advanced multiphysics modeling and simulation efforts in Ft. Belvoir, VA. In this role, you will contribute to high-impact government contracts focused on conventional weapons effects, computational structural dynamics, computational fluid dynamics, and multi-spectrum functional defeat modeling. The ideal candidate brings a strong physics foundation, hands-on simulation experience, and the ability to operate effectively within a collaborative, fast-paced technical environment supporting national defense priorities.

Key Responsibilities:

Develop, execute, and validate Computational Structural Dynamics (CSD) and Computational Fluid Dynamics (CFD) models to support conventional weapons effects analysis
Perform coupled CFD/CSD simulations to characterize complex fluid-structure interaction phenomena under operationally relevant conditions
Conduct thermal modeling to assess heat transfer, thermal loading, and material response in weapons effects scenarios
Build and apply multi-spectrum functional defeat models to evaluate target vulnerability and system defeat mechanisms across relevant threat profiles
Support the development and maintenance of conventional weapons effects models in compliance with program-specific requirements and standards
Execute rigorous uncertainty analysis to quantify and communicate model fidelity, sensitivity, and confidence bounds to stakeholders
Collaborate with interdisciplinary teams of physicists, engineers, and analysts to integrate simulation outputs into broader system-level assessments and technical reports

Required Qualifications

Bachelor's degree in Physics, Applied Physics, Mechanical Engineering, or a closely related STEM discipline (Master's preferred)

8+ years of experience in multiphysics modeling and simulation, consistent with a journeyman proficiency level
Demonstrated hands-on experience with CFD and/or CSD modeling tools (e.g., ANSYS, LS-DYNA, ABAQUS, OpenFOAM, AUTODYN, or equivalent)
Working knowledge of coupled multi-physics simulation methodologies, including fluid-structure interaction
Familiarity with uncertainty quantification (UQ) methods and their application in physics-based modeling environments
US Citizen with an Active Top Secret / SCI security clearance (required at time of application)
Strong written and verbal communication skills with the ability to document and present technical findings clearly to both technical and programmatic audiences

Desired Qualifications

Experience with conventional munitions, terminal ballistics, or weapons effects modeling in a DoW or DOE-related program environment
Familiarity with multi-spectrum target defeat analysis or vulnerability/lethality (V/L) assessments
Experience working within a government contracting environment, including adherence to SOW deliverables, CDRLs, and program schedules
Proficiency in scripting or programming languages (Python, MATLAB, or Fortran) for pre/post-processing and automation of simulation workflows

Company Description

The Red Gate Group, founded in 2006, is a Service-Disabled Veteran-Owned Company based in Chantilly, VA.
